A handle taping system provides a mechanism for a taping station that is actuated by the passage of any of a variety of articles or products being conveyed therepast. A length of a first pressure sensitive carrier tape, whose length is automatically determined in accordance with the length of the article is applied in adhering relation to the leading face of the article and the tape drawn lengthwise from the reel by passage of the article therealong. A second, blanking ribbon is released in adhering relation with the first tape, having the pressure sensitive adherent face of the tape pressed in securing relation with the ribbon, to form a handle portion. As the article trailing end passes a first limit switch the blanking ribbon is automatically severed, thus limiting the length of the blanked handle portion of the first tape to a desired length relative to the length of the article. Subsequent passage of the article trailing end past a second switch reattaches the ribbon to the first tape, thus leaving a residual, unmasked intermediate attachment portion of first tape, which portion is automatically divided to provide a trailing end tab, and a leading end attachment tab for the succeeding article's handle. The trailing end tab is adhered to the article, generally down the trailing end face of the article, to thereby fix the handle in securely attached relation. In another embodiment, blanking of the handle outer face is provided by the application of an inert filler or deactivating fluid or thereto as an adhesive suppressant.
